Hybrid Services and Connector Troubleshooting
In this articleYou may encounter some issues in your Cisco Webex Hybrid Services deployment. On Expressway, you can use troubleshooting tools, capture logs, restart a connector, or roll back to a previous version of a connector.
Diagnostic Tools on Expressway-C Connector Host
Use these diagnostic tools to investigate a problem with Hybrid Services connectors that are installed on the Expressway-C.
Access the Webex Hybrid Services log levels and enable debug mode if instructed to do so by support. Go to Maintenance > Diagnostics > Hybrid Services Log Levels.
-
Check the event log for errors and warnings. Go to .
-
Check for related alarms on . Alarms that are related to Hybrid Services are tagged [Hybrid Services] and have IDs in the 60000–69999 range. You can also see these alarms in Control Hub ( https://admin.webex.com).

-
Take a system snapshot to provide to support for diagnosis. Go to .
-
Configure syslog if you have remote logging servers. Go to .
-
Configure incident reporting so that any Expressway failures are automatically reported to us. Go to .

Check Connector Health on Expressway-C
When you're having a problem with Hybrid Services, you can check the status of the connectors and restart any stopped connectors.
Before you begin
If a connector is stopped, you can open a ticket with support and send a log first before you restart the connector.
| 1 |
On the Expressway-C, go to to check the status of your connectors. The Connector Management section shows all the installed connectors, their version numbers and their status. |
| 2 |
If a connector is Stopped, click the name of that connector. You'll see a more detailed status page with a Restart button. |
| 3 |
Click Restart. |
What to do next
If the restart generates an alarm, or if the connector stops again, try the following:
Follow the guidance on the alarm. You can also see these alarms in Control Hub ( https://admin.webex.com).
-
From the customer view in https://admin.webex.com, click your username, and then click Feedback to open a ticket and send logs.
-
Use the diagnostic tools to look for problem signatures.
-
Roll back to the previous version of the connector (try this if the problem started after a connector upgrade).
Roll Back to the Previous Version of a Connector
Under normal conditions, your Expressway-C upgrades your connectors automatically after you choose to upgrade in Control Hub or set a scheduled upgrade time. You can roll back to the previous version of a connector if something goes wrong with an upgraded connector.
| 1 |
On the Expressway-C, go to to check the health status of your connectors. The Connector Management section shows all the installed connectors, their version numbers, and their status. |
| 2 |
Click the name of the connector. A more detailed status page shows the currently installed version and the version that you can roll back to. The page also shows any versions that you previously rejected (by rolling back from them). |
| 3 |
Click Roll back to reject the currently installed version, and replace it with the Target version. The page displays the formerly installed version number in the Rejected version field, which means that the will not allow that version to install itself in future. If you click Back to connector list, you can see the previous version is now running. An alarm is raised because you rejected an upgrade. You can safely ignore that alarm; it appears because of your choice, and it is lowered when a newer version is installed. When a newer version is available on Webex, the automatic upgrade resumes. |

To reverse your decision and accept the Rejected version, click Allow this upgrade. |
